Operating device for push button-dialled telephone

ABSTRACT

An operating device for a push button dialled telephone in which pressers driven by electromagnetic solenoids are provided opposite to push buttons of the push button dialled telephone and the push buttons are depressed as desired with a power supply appropriately controlled by said electromagnetic solenoids. Dialling operation can be performed, without touching a finger directly on the push buttons, by means of an additional device for generating automatically a variety of controlled electrical signals.
